FMC Carrier Card Linux User IO Tutorial

This tutorial interfaces the Zynq processing system (PS) through routing resources inside the programmable logic (PL). A Linux application controls the blink pattern and rate of the four LEDs on the FMC-CC. This is done with the built-in PS GPIO controller. The LEDs are controlled by input through the two push buttons. This is the tutorial referred to in the Quick Start Instructions and the Getting Started Guide.
